Measurement of heavy-flavor electron production in Au+Au collisions at root sNN = 5 4. 4 GeV at STAR
Original language description
Studying heavy-flavor production in high-energy heavy-ion collisions (HIC) can enhance our comprehension of parton interactions with the quark-gluon plasma (QGP) created in these collisions. Due to their significant mass, heavy quarks (charm and bottom) are mainly generated during the initial phase of HIC when hard scatterings are prevalent, and experience the entire evolution of the QGP. One way to study heavy quarks is through the measurement of electrons from heavy-flavor hadron decay, heavy-flavor electrons (HFE). In this contribution, we present the analysis of HFE at low transverse momentum (pT) in Au+Au collisions at root sNN=54.4GeV using data taken in 2017 by the STAR experiment. The strong HFE suppression was already observed in the central Au+Au collisions at root sNN=200GeV. Measuring heavy-flavor quark nuclear modification factors below the RHIC top energy offers new insights on the in-medium energy loss, especially the collisional energy loss which is dominant at low pT.
